1. The white GUI on black background is garish and downright painful to look at.
21. There is no "you have posted in this thread" marker when you view "Today's Posts"
22. There is no easy way to "find all posts by X person" (a tool I used to track threads I posted in, and see responses.)
#1 was killing me when I was trying to find if my issues were on the list.
Anyways, yeah the lack of being able to see which threads I posted in to check for replies makes it harder to offer rebuttals on discussions unless I write down which threads I posted in.
